What Is The Difference Between A Bone Scan And A PET Scan?

How long does it take to get the results of a bone scan?

A radiologist will interpret the images, write a report, and deliver the results to your doctor via the internal computer system.

This process usually takes less than 24 hours..

What does a hot spot on a bone scan mean?

The areas where the radionuclide collects are called “hot spots,” and may indicate the presence of conditions such as arthritis , malignant (cancerous) bone tumors , metastatic bone cancer (cancer which has spread from another site, such as the lungs), bone infections , bone trauma not seen on ordinary X-rays, and …

Can I wear a bra for a bone density test?

Do not wear jewelry, hearing aids, belt buckles, zippers, snaps, or buttons. Females should wear a sports bra. Bras with under wires will need to be removed. It is okay to eat anytime before or after the exam.

Does a bone tumor hurt?

Pain in the affected bone is the most common sign of bone cancer. At first, the pain is not constant. It may be worse at night or when the bone is used, for instance, leg pain when walking. As the cancer grows, the pain will be there all the time, and get worse with activity.

What should you not do before a bone density test?

Is there a prep for a bone density test?Stop taking calcium supplements, multivitamins and antacids, such as Tums, for 24 hours before your test.If you have had a barium or contrast x-ray exam, wait for 10 days afterwards to schedule your bone density test.

Can a bone scan detect cancer?

Your doctor may order a bone scan if you have unexplained skeletal pain, a bone infection or a bone injury that can’t be seen on a standard X-ray. A bone scan can also be an important tool for detecting cancer that has spread (metastasized) to the bone from the tumor’s original location, such as the breast or prostate.

Do you have to take your clothes off for a bone scan?

You may have to wait several hours between the radiotracer injection and the bone scan so you may want to bring something to read or work on. Leave jewelry at home and wear loose, comfortable clothing. You may be asked to wear a gown.

Does a bone scan show osteoporosis?

To diagnose osteoporosis and assess your risk of fracture and determine your need for treatment, your doctor will most likely order a bone density scan. This exam is used to measure bone mineral density (BMD). It is most commonly performed using dual-energy x-ray absorptiometry (DXA or DEXA) or bone densitometry.

What is a PET bone scan?

A PET/CT scan with sodium fluoride F 18 injection (18F NaF) is a nuclear imaging test that scans the entire skeletal system and produces high-resolution images of the bones. These images are used to detect areas of abnormal bone growth associated with tumors.

What does a bone scan show that an MRI doesn t?

A bone scan is an imaging test used to help diagnose problems with your bones. It safely uses a very small amount of a radioactive drug called a radiopharmaceutical. It has also been referred to as a “dye,” but it doesn’t stain the tissue. Specifically, a bone scan is done to reveal problems with bone metabolism.

What are the disadvantages of a PET scan?

Disadvantages of PET/CT Scans Because the radioactive material is combined with glucose and then injected into the patient, this can be a concern for some diabetic patients. Before having a PET/CT scan, a diabetic patient’s blood sugar level will be evaluated, and a glucose serum blood test might be administered.

What are the side effects of having a PET scan?

If undergoing a combination PET-CT scan, the iodine-based contrast dye used for the CT component can cause side effects, including nausea, vomiting, headache, itching, flushing, and mild rash. In rare cases, a serious, all-body allergic reaction known as anaphylaxis may occur.

Which is better bone scan or PET scan?

In general, osteoblastic lesions are more readily detectable by bone scan and osteolytic lesions from glucose-avid primary malignancies are more readily detectable by FDG PET/CT. Overall, PET/CT is shown to be more specific for metastatic disease than bone scan.

Is a bone scan better than a CT scan?

CT scans of the bones can provide more detailed information about the bone tissue and bone structure than standard X-rays of the bone, thus providing more information related to injuries and/or diseases of the bone.

How small of a tumor can a PET scan detect?

PET scans may play a role in determining whether a mass is cancerous. However, PET scans are more accurate in detecting larger and more aggressive tumors than they are in locating tumors that are smaller than 8 mm a pinky nail (or half of a thumb nail) and/or less aggressive cancers.

How long does a full body PET scan take?

How long does a PET scan take? A PET scan will take about 60 to 90 minutes for the radiotracer to start working, depending on what type of information your doctor is looking for.

Does inflammation show up on a bone scan?

Bone scan is one of the most common and oldest examinations among all nuclear medicine procedures. It is used in the evaluation of benign bone disease like infection/inflammation and also is the standard of care for evaluating metastatic disease in the breast, prostate, and lung cancer.
